In this paper we introduce a surgical procedure, called a rational blowdown, for a smooth 4-manifold X and determine how this procedure affects both the Donaldson and Seiberg-Witten invariants of X. Source: http://arxiv.org/abs/alg-geom/9505018v1
In this paper we present a formula which relates the Donaldson invariants of a 4-manifold X with the Donaldson invariants of its blowup X#-CP(2). This blow-up formula is independent of X and involves sigma-functions associated to a naturally arising elliptic function. This, the final version, corrects some earlier misconceptions regarding signs. Source: http://arxiv.org/abs/alg-geom/9405002v2
My grandson, Finn, age 9 mo., pursues a ball, crawling, "talking," sitting, and laughing. Watch him recognize an obstacle, maneuver through it, then forget the vertical clearance issue. Notice the expression on his face at the end when he turns his head in response to his grandmother calling his name. Topic: baby

This is an audio message that was ministered in our Live Voice Conference in Beyond the Veil Prophetic Ministries presented by Rev. Amanda Connell. The subject of the message is called "Reflecting the Divine Nature of God." In this message Rev.Amanda discusses four relevant areas of the Nature of God that is designed for the beginner believer, or the advanced. We pray it is a blessing to you, today.

I develop n-site cluster approximations for a stochastic sandpile in one dimension. A height restriction is imposed to limit the number of states: each site can harbor at most two particles (height z_i \leq 2). (This yields a considerable simplification over the unrestricted case, in which the number of states per site is unbounded.) On the basis of results for n \leq 11 sites, I estimate the critical particle density as zeta_c = 0.930(1), in good agreement with simulations. A coherent anomaly...

A question of Jack Morava is answered by generalising the notion of Moore paths to that of Moore hyperrectangles, so obtaining a strict cubical omega-category. This also has the structure of connections in the sense of Brown and Higgins, but cancellation of connections does not hold. Source: http://arxiv.org/abs/0909.2212v4
Monte Carlo simulations have been used to study a discretized Heisenberg ferromagnet (FM) with random uniaxial single-site anisotropy on $L \times L \times L$ simple cubic lattices, for $L$ up to 64. The spin variable on each site is chosen from the twelve  directions. The random anisotropy has infinite strength and a random direction on a fraction $x$ of the sites of the lattice, and is zero on the remaining sites. In many respects the behavior of this model is qualitatively similar to... Source: http://arxiv.org/abs/cond-mat/9801033v1
We compute the structure relations in special A_\infty-bialgebras whose operations are limited to those defining the underlying A_\infty-(co)algebra substructure. Such bialgebras appear as the homology of certain loop spaces. Whereas structure relations in general A_\infty-bialgebras depend upon the combinatorics of permutahedra, only Stasheff's associahedra are required here. Source: http://arxiv.org/abs/math/0506446v2
We apply the Transfer Algorithm introduced in arXiv:1106.5090 to transfer an A_\infty-algebra structure that cannot be computed using the classical Basic Perturbation Lemma. We construct a space X whose (base pointed) loop cohomology H = H^*(\Omega X; Z_2) comes equipped with a nontrivial operation \omega : H x H --> H x H. Source: http://arxiv.org/abs/1108.5693v9
Applied to the master equation, the usual numerical integration methods, such as Runge-Kutta, become inefficient when the rates associated with various transitions differ by several orders of magnitude. We introduce an integration scheme that remains stable with much larger time increments than can be used in standard methods. When only the stationary distribution is required, a direct iteration method is even more rapid; this method may be extended to construct the quasi-stationary...

Clinical and legal decisions may be influenced by findings that suggest marijuana use during treatment serves as an obstacle to treatment success, compromises treatment integrity, or increases the prevalence or...
